摘      要：The crown form of maxillary central incisor tooth is one of the vital phenomenon for a person’s *** crown form has been compared with other anatomical parameters such as arch form and facial *** different classes of tooth forms which relate to square,tapered,and ovoid forms are *** aim of this study was to morphometrically evaluate the correlation between maxillary dental arch form and the maxillary central incisor crown *** cast models of fifty male and fifty female normal occlusion controls in the age group of 18-23 years were *** mesiodistal(MD)dimensions of the maxillary central incisors were measured at incisal(MD_I)and at gingival(MD_G)*** transverse widths of maxillary casts were measured at the first molar and at the first premolar *** measured data were statistically analyzed using the SPSS *** MD dimensions of maxillary central incisor were significantly greater in males than *** ratio between the two MD dimensions also varied significantly among *** intermolar width(IMW)and interfirst premolar width(IPmW)between males and females were highly significant(P0.05),whereas the ratio between these two parameters in males and females was not significant(P=0.43).Eighty‑eight percentage of the participants were found to have an ovoid type of maxillary arch,while only 45%of them had the ovoid form of maxillary central *** MD_I and the IMW were found to be in the ratio of 1:5.5 in both *** MD_G and the IPmW were in the ratio of 1:4.7 in males and 1:4.5 in *** was a weak positive correlation between MD_I and IMW(r^(2)=0.146)and between MD_G and IPmW(r^(2)=0.05).No significant concordance between the maxillary central incisor crown form and the maxillary arch form was found in this study.
